|Curator's note: This piece by Rich Samuels first aired on WTTW's "Chicago Tonight" show on November 25, 2008. It raises the issue of whether the flow of the Chicago River might be reversed as part of a process to separate Lake Michigan (and the Great Lakes) from the Mississippi River system. Among other things, it would help keep invasive species like the Asian Carp out of the Great Lakes. On September 10, 2010, Chicago Mayor Richard Daley told the Chicago Tribune that the time had come to undertake this project. Among those featured in this piece are Joel Brammeier of the Alliance for the Great Lakes and John Rogner who, at the time this piece first aired, was with the US. Fish and Wildlife Service.
